Well what I see from your other post is that the movies work perfectly find in your panasonic bd35 but they only read as a data disc in your ps3. (as per this post) Now when the disc is in your panasonic, does it say it is a bluray disc, an avchd disc, or something else? I honestly have not played with dual layer bd as they are too expensive, but I have fooled around with single layer like mad. What I would suggest is try it on a RE disc and see if it will play on your pc first. Actually what I do is create an image, mount it and check before I burn it just so I do not waste media, and 45 minutes. If it plays, then it will play fine.
Make sure you are only using udf 2.5, which you prolly already are, but just in case make sure no iso9660 or joliet listing in your file system. The newest versions of image burn SHOULD be auto selecting this for you, but check just to make sure.
You could also try running the files through bd-rebuilder and see if everything is compliant.
